===71152S - Semi-annual Trend Problem Identification and Resolution
Semi-annual Trend Review (Section 03.02)===
- (1) The inspectors reviewed the licensees corrective action program for potential emerging or adverse trends that might be indicative of a more significant safety issue.
INSPECTION RESULTS
Assessment: Corrective Action Program Semi-annual Trend Review 71152S The inspectors reviewed Constellations corrective action program and evaluated a sample of issues and events that occurred from January 2022 through June 2022 at Ginna. The inspectors then verified whether the issues were appropriately evaluated by Constellation for emerging or adverse trends and addressed within the scope of the corrective action program or through department review.
The inspection did not reveal any new trends that could indicate a more significant safety issue. The inspectors determined that Constellation personnel were identifying trend issues at a low threshold and entered them into the corrective action program for resolution. The inspectors noted low level or precursor trends identified by Constellation relating to the following: RM-14A radiation monitor, offsite circuit manhole float switches, configuration control, human performance precursors, and cold weather issues. The inspectors noted several issue reports relating to emergency light failures. The inspectors discussed the circumstances of the failures with Constellation staff and verified actions were in place to correct the deficiencies. As a result, the inspectors determined station emergency light deficiencies were being entered and trended in the corrective action program.
Based on the overall results of the semi-annual trend review, the inspectors determined that Constellation had properly identified adverse trends at Ginna before they became more significant safety problems. The inspectors independently evaluated the deficiencies noted above for significance in accordance with the guidance in Inspection Manual Chapter 0612, Appendix B, Issue Screening, and Appendix E, Examples of Minor Issues. The inspectors determined that none of the conditions were deficiencies of greater than minor significance and, therefore, are not subject to enforcement action in accordance with the NRCs Enforcement Policy.
